The single microbe that kills the most humans in 2016 is not Ebola, not Zika, not brain-eating amoebas. It is not an infection that continually grabs headlines. It is Mycobacterium tuberculosis, a profligate killer that has menaced humans since our appearance on the planet. In 2014, tuberculosis felled 1.5 million humans.

Discovering Tuberculosis is a scholarly work that takes the reader through several important phases in the control of tuberculosis with attention to the principles at play in each of them. From efforts to control TB on Native American reservations to the global fight against HIV/TB coinfection, McMillen skillfully makes the past not just come alive but completely inform how we presently face this infection.

Some important highlights of the book include the failure of the BCG vaccine and how this vaccine may have stymied vaccine development more generally; the early harbingers of the threat of drug resistant TB in 1960s Kenya; the vicissitudes of the approach to HIV/TB coinfection, and the not often mentioned negative effects of directly observed therapy.

One of the most important aspects of this book is that it relies on Professor McMillen's extensive review of the actual communications between programmatic leaders and health agencies. Such a level of granularity grounds his analysis in the actual medical debates that were occurring, allowing almost direct application to current efforts.

Discovering Tuberculosis allowed me to gain a better understanding of today's global anti-tuberculosis effort and grasp how difficult it will be to rid our race of its most astute infectious disease killer. I highly recommend it.
